MACHINE FOR OPERATING TTPON'SOLES.

Patented Apr. is, 1916.

Application filed August 28, 1913. Serial No. 787,147.

T 0 all whom it may concern:

Be it known that I, Join: J. DONLON, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Operating upon Soles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a machine for operating upon soles after they have been incorporated in boots or shoes and more particularly to machines of this character which perform the operations of laying the channel flap and leveling the sole.

In the majority of shoes it is customary to form a channel in the marginal portion of the sole surface to receive the line of stitches securing the outsole to the lasted shoe. After the sole has been incorporated in the shoe and prior to the leveling or forming of the sole to its final shape it is necessary to lay and smooth channel in order that the surface of the sole after leveling shall present a smooth unbroken appearance. In the manufacture of that class of shoes which are leveled by direct pressure it has been customary heretofort to perform the operation of laying the channel flap either upon a separate machine, or more commonly, by a manual operation after the shoe has been jacked upon the levcling machine. It will be obvious to those skilled in the art that both of these methods are more or less objectionable as the first involves a certain loss of time which must elapse between the two operations and in the second method the character of the work erformed and the length of time necessary to lay the channel flap depend wholly upon the care and skill of the operator.

One object of the present invention is to provide a machine which shall perform the two separate operations of laying the channel flap and leveling the solo by direct pressure Without requiring any manual interferonce upon the part of the operator.

-With this object in view, one feature of the invention consists in the combination of a shoe supporting member, a pressing member, means for relatively actuating the members to level the sole by direct pressure, and

out the flap covering this mpans for laying the channel flap of a shoe so .e.

Another feature of the invention contemplates the provision in a machine of the class described, having a pressing form, a shoe supporting pick, and means for moving the ack inwardly and upwardly from a posit1on of presentation to a position of pressure, of means actuated upon theinward movement of the jack to lay the channel flap of the sole.

A further feature of the invention consists 1n the provision of mechanism for causing the flap laying device to operatively engage with the sole during the movement of the ack in one direction and for retaining the flap laying device out of operativeengagement with the sole during the movement of the jack in the opposite direction. In the simplest and most efficient form of the invention WlllCh has yet been devised the flap laying device engages with the sole during the movement of the jack from a position of presentation to a position of pressure and is removed from operative engagement with the sole during the movement of the jack in the opposite direction.

Still further features of the invention consist in certain novel features of construction, combinations, and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the accompanying drawings illustrat ing the preferred form of the invention, Figure 1 represents a partial side elevation of a machine embodying the several features of the invention in their preferred form; Fig. 2 is a detail illustrating a front elevation partly in section of a jack and the cooperating channel flap laying mechanism; and Fig. 3 is a detail showing a side elevation of the mechanism illustrated in Fig. 2.

The illustrated embodiment of the invention is shown in connection with a machine of the type disclosed in the U. S. Patent t0 Mayo, No. 845,714, dated February 26, 1907, but it is to be understood that the invention may also be embodied advantageously in other machines of this type which shape the solo by a direct pressure.

The machine is provided with a shoe supporting jack 1 constructed to receive a last which is through mechanism not shown.

. 5 a cam 10 actuated by or follower 2 which cooperates with a pressing form 3 to level the shoe by a direct pressure. The jack is arranged to reciprocate in horizontal guideways formed in a table 5 moved vertically in the machine The jack is moved from a position ofpresentation to a position beneath the pressing form, and vice versa, by a lever 8 and link 9 actuated in the usual manner After' the jack has been moved. to a position directly beneath the form, the latter is released and allowed to seat itself by gravity upon the shoe, in which position it is looked through the connecting rod 11. An upward movement is then imparted to the table to apply the pressure to the sole through a toggle joint, one member of which is indicated at 12. As this mechanism is frame 6.

I old and well-known in the art and is fully disclosed in the patent above referred to, it has been only briefly described herein. It has been usual heretofore when leveling the sole in this manner to first jack the shoe and 5 lay the channel flap by rubbing out the marginal portions of the sole manually. In the present invention this mode of operation has been improved by causing the channel flap laying operation to be performed mechanically by the machine after the shoe has been jacked and prior to the leveling of the sole.

In the simplest and most efficient form of the invention which has yet been devised 1 the inward movement of the jack from a position of presentation to a position of clearance beneath the form is utilized to lay the channel 'fiap, thus enabling this added operation to be performed without varying the the end of the carrier slides and the bottom of the slot is provided with a recess 25 in which the spring 26 is seated. With this construction, as the jack is moved beneath press the roll carrier through the springs 2& until the rolls engage with the shoe sole, the springs 26 yielding to allow this movement to take place. In order that the rolls may accommodate themselves to the varying curvature of different portions of the sole the outer end of each roll is provided with a stud 28 which is loosely received in a recess 29 formed in the carrier 18. The inner ends of the rolls are operatively connected through a spherical member 31 engaging with corresponding recesses formed in the adjacent faces of the rolls and are maintained in operative engagement with the sole by a pair of plungers 33 slidingly supported in the carrier and yieldingly pressed against the rolls by'springs 35. It will be evident from the above described construction that the rolls will be turned by contact with the sole as the shoe moves thereunder and in order to cause this movement to rub the margins of thesole outwardly each roll is providedwith a spiral groove of suitable form as shown clearly in Although it is desirable that the marginal portions of the sole shall be rubbed outwardly prior to the leveling operation in order to cause the surface of the sole to present a smooth, unbroken appearance after it has been leveled, it is further desirable that the flap laying devices shall be removed from contact with the sole during the return movement of the jack to a position of the rolls the levers 22 are actuated to de-- presentation To this end each lever 22 is provided with an inwardly extending arm 40 which is engaged by-an arm 42 loosely .fulcrumed upon the inside of the standard at 23. The arm and lever are so arranged that as the jack moves inwardly from a position of presentation toa position of clearance beneath the form the arm 42 engages with the arm 40 and through the latter actuates the lever to depress the roll carrier. Upon the return movement of the jack, 11 however, the arm 42 is swung in the oppo- 40 mode of operation of the machine or necessitating any greater length of time than is required for performing the leveling operation alone j I In theillustrated embodiment of the in- 45 ventiona pair of flap laying rolls 15 are supported above the last 2 by standards 16 rigidly secured to the table 5. The two rolls are loosely journaled at their outer ends in a roll carrier 18 slidingly mounted in the to standards 16 and having its opposite ends operatively connected to cams 20 mounted 55 the sole.

upon the jack 1 and so arranged that as the jack is moved beneath the rolls the latter are depressed to engage with the surface of Each endof the carrier is connected to its respective cam through a lever 22 fulcrumed upon the standard at 23 and connected to the carrier at one end through a tension spring as The rolls are normally a site direction and the movement of the arm through contact with the cam 20 does not effect the lever 22. In order to allow the arm 42 to swing in the opposite direction upon the return movement of the jack the cam 20 is provided with a recessed portion 45, as shown clearly in Figs. 1 and 3.

The operation of the improved mecha- 60 elevated above the level of the sole by a n-iSm is as follows':-Af ter the shoe has been pair of springs 26 interposed between the jacked the machine is started and the jack ends of the carrier 18 and the standards 16. is first moved inwardly on the table from a As shown clearly in Figs.'2 and 3 of the position of presentation to a position of drawings the upper end of each standard is clearance beneath the, form. During this as provided with a longitudinal slot in which movement the rolls are yieldingly pressed 1 against the sole by the cams 20 and the relative traverse of the rolls and jack causes the former to rub the margins of the sole outwardly. Owing to the manner in which they are supported the rolls are free to tip in any direction as the shoe passes thereunder to conform to the varying curvature of the sole. After the jack has reached a position of clearance the form is moved to seat it upon the sole and the table is then actuated to cause the form to press the surface of the sole. After the pressing operation is completed the a'ck is returned to its initial position and the cam 20 and arm 42 are so constructed and arranged that this return movement does not afl'ect the rolls 15 which are retained in an elevated position by the springs 25, thus causing the rolls to operatively engage with the sole prior to the leveling operation only.

\Vhile it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this constrution and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention.
